Kinematic Structure in the Galactic Halo at the North Galactic Pole: RR Lyrae and BHB Stars show different kinematics
T. D. Kinman, C. Cacciari, A. Bragaglia +2
Space motions are given for 38 RR Lyrae (RRL) stars and 79 blue horizontal branch (BHB) stars in a ~200 deg2 area around the North Galactic Pole (NGP) using a homogeneous distance…
Synthetic Mid-UV Spectroscopic Indices of Stars
M. Chavez, E. Bertone, A. Buzzoni +4
Using the UVBLUE library of synthetic stellar spectra we have computed a set of mid-UV line and continuum spectroscopic indices. We explore their behavior in terms of the leading s…
High-resolution spectroscopy of RGB stars in the Sagittarius Streams. I. Radial velocities and chemical abundances
L. Monaco, M. Bellazzini, P. Bonifacio +5
Context. The Sagittarius (Sgr) dwarf spheroidal galaxy is currently being disrupted under the strain of the Milky Way. A reliable reconstruction of Sgr star formation history can o…
An updated survey of globular clusters in M 31. I. Classification and radial velocity for 76 candidate clusters
S. Galleti, L. Federici, M. Bellazzini +2
Aims - We present the first results of a large spectroscopic survey of globular clusters and candidate globular clusters in the nearby M~31 galaxy. The survey is aimed at the class…
Planetary nebulae as tracers of galaxy stellar populations
A. Buzzoni, M. Arnaboldi, R. L. M. Corradi
We address the general problem of the luminosity-specific planetary nebula (PN) number, defined as alpha = N(PN)/L(gal), and its relationship with age and metallicity of the parent…
